Vercel v0.
From prompt to deployed UI — Next.js + AI SDK runtime.
What it is.
Vercel's AI builder. Generates Next.js applications from prompts, deploys them on Vercel's edge runtime, and hands the code back as a real repository. The AI SDK underneath is the most-deployed JavaScript chat-and-agent runtime — used by Perplexity, Vercel themselves, and a long list of consumer AI products.
Where it fits.
Front-end and product teams that want to ship working UI from a prompt and inherit Vercel's deploy story. Strongest when the buyer is already on Next.js. The AI SDK alone is justification for adoption even without v0 generation.
- Production-quality Next.js output
- Edge runtime included via Vercel deploy
- AI SDK is the default JavaScript LLM library
- Output quality drops outside React and Next.js conventions
- Lock-in to Vercel runtime for hosted projects
Frequently asked.
Does v0 output a real repository?
Yes. Export to GitHub with full source. The most useful difference from Bolt and Lovable — buyer owns the code outright.
What is the AI SDK?
Vercel's JavaScript and TypeScript SDK for LLM applications. Multi-model, streaming-first, framework-agnostic. The dominant LLM library in the JavaScript ecosystem.
Can v0 work with my design system?
Yes via uploaded references and component libraries. Default output uses shadcn/ui, which most teams adapt rather than replace.
